Nice helpful idea but I think
lots of problems involved.
What happens if something gets lost in the post?
Post office obviously - there is no other way to send the equipment but by any kind of insured service - Parcelforce for example
Who is responsiblle for damage while in use.
That...
Hi,
I know that for majority of you this idea my sound crazy but I myself came across that issue many times. There are several projects that I can't finish due to lack of specific equiment needs - for example I want to build 4.5 digit multimeter. One option is to buy resistor with very tight...
Just checked them and
1) not in UK as far as I have noticed
2) 2 layer no solder mask 100mm x 100mm costs 40GBP
3)A4 front panel with simple cutouts and 50 letters of engraved txt costs 80EUR 2mm black anodized aluminium
For many amateurs it is just overkill-what I am looking to do is something...
Hi,
I am trying to figure out how many people in UK would be interested in rapid PCB Prototyping services - probably up to 2 layer PCB at start and Custom Enclosure services.
Generally speaking I am thinking about opening my own business where I would build low volume PCB Prototypes as well as...
Re: What kind of slew rate should I expect from LM 741 op am
well tried this configuration, but noticed one strange thing on the rising slope got bout 1V/us slew rate on falling edge got 0.575V/us...so which I should use for measuring a slew rate?

Re: What kind of slew rate should I expect from LM 741 op am
obtained 5 more 741 op amps and tested agains the other one I had, well they were pretty close together in terms of the Slew Rate the value oscillated around 0.79-0.85. They were all from the same batch so I would say it was expected...
Re: What kind of slew rate should I expect from LM 741 op am
unfortunately I don't have more of 741 op amps,but I had several of TL072 op amps, their min slew rate is 5V/us , with typical of 13V/us. I checked 3 of them and I had this results: 14.11V/us 15.48V/us and 13.71V/us , so they swing...
Re: What kind of slew rate should I expect from LM 741 op am
well problem is that I am trying to find somewhere over the internet an 741 op amp with slew rate more than 0.5 V/us and cant find any reference, thus it makes me hard to understand my results.
Re: What kind of slew rate should I expect from LM 741 op am
I am not bothered about the vendor or the time when the IC was produced, but obviously when I will write the report the question that will need to be answered is why the slew rate is so different from the datasheet typical value, and...
Re: What kind of slew rate should I expect from LM 741 op am
I think that they are from the same vendor, yet definitely from different batches, mine was bought 2 days ago, the one at college could be years old or more. I got +-16.3V college one had a +-15V, but shouldn't slew rate be kind of...
Hi,
I did an lab exercise and had a result of Slew Rate around 0.75V/us. Wanted to recreate the exercise at home and build the same circuit - an astable multivibrator with feedback resistor of 20kOhm, 100nF cap connected to negative input. 10kOhm resistor at the output going to the positive...
